never would have happened on Uli's watch!

though whether that would be because he'd catch it or just have never applied the patch, who knows!

I know of one such patch he rejected. The semaphores in shared memory using sem_init are a different size for 32-bit binaries and 64-bit binaries, meaning that semaphore can't be shared by 32-bit and 64-bit binaries. A change was proposed to change the 32-bit version to be compatible with the 64-bit version, and it was rapidly shot down by Uli for breaking API compatibility.

What about the "extern int errno" business? (Yes, I know, that's pretty lame, but it still hurt when you were affected by it.)
